Fig. X is a View of one of the shaft I, between the spiders E, having pend- IOO out weights N preventing their rotation with the shaft and carrying upwardly-projecting arms 0, which serve the purpose of preventing the cotton from wrapping around the shaft, causing its deflection toward the periphery of the cylinder and thus keeping the cylinder from clogging. The entire interior of the cylinder is preferably covered with emery or sand concrete. The fan, if preferred, may be arranged at the end of the cylinder O, as shown in Fig. IX, and coaxially therewith. In either case air-passages are provided from the cylinder to the fan-casing through suitable apertures K, Figs. VIII and of which the upper and principal portion of the cylinder is made up, are fixed rubbers, which consist in part of blocks'L, of leather or other material coated with emery, and in part of radial arms 0, formed of iron roughened on their surfaces and coated with emery, as described with reference to thespider-arms Z, which arms 0 co-operate with the arms E as the latter pass between them in separating the lint from the seed; or, if preferred, the rubber blocks L may be dispensed with .and the roughened arms 0 extend from end to end of the cylinder, as illustrated in Fig.

IX. These arms 0 may be inclined, as shown in Fig. XI, if desired. The cleansed seed is discharged through a suitablespout Q. The ends of the frame are braced and connected by suitable ties R, and are provided with the necessary journal-boxes S and T forthe main shaft I and fan-shaft J ,.respectively. 7 The rubbers M, curved arms Z, and fixed rubbingsurfaces L and 0 may be inclined obliquely from the feeding to the discharge end of the cylinder in order to cause a gradual longitudinal feed of the material to be effected by the rotation of the shaft and its arms, as shown in Fig. XII.

The staves H, of which the cylinder is made up, may be mounted with a slight space between them to more freely aspirate the interior of the cylinder, giving vent to the fan and causinga more active circulation through the cyllnder by which the lint is drawn from theseed as soon as detachedby the scouring action. The lint is either blown to a condenser orto a dust-room.

The feed of the machine may be effected by any suitable wellknown automatic-device regulated as required, and as the seed is carried through the cylinder by the slight incline in the fixed rubbing-faces L or in the blocks M, or both, it is constantly caught by the rotary arms and rubbers, whirled around the cylinders, and quickly cleansed of lint and impurities by the friction, the cleaned seed, the cotton,and the motes and imperfect seed and other impurities being automatically separated and discharged at different places, as above described.

If preferred,a portion of the staves or slats that form the cylinder may be covered with wire-cloth tacked thereon to provide a scouring-snrface, as shown in Fig III Such wirecovered slats are used at some points w1th1n the cylinder where the friction would be too great for the use of emery, as first described. In the drawings it is shown at the feeding end of the cylinder where the broad rubbers M are located.

Having thus described my invention, the

' following is what I claim as new therein and On the inner faces of the stares H, Fig. VI,

desire to secure by Letters Patent:

1. A cotton-seed-linting machine constructed, substantially as herein described, with a casing provided with openings for the admission of air, a fan communicating with the interior of the casing, arms or pro ections fixed within the casing, a rotary shaft carrying arms for producing friction upon the seed in conjunction with the fixed arms or projections, and a suitable feed-hopper and discharge-spout. for'the seed, said arms being inclined obliquely from the feed to the discharge end of the cylinder, substantially as set forth.

2. The combination of the casing provided wit-l1 air-openings, a fan communicating with said casing, arms or projections fixed within the casing, and a rotary shaft having arms for co-operating with said fixed arms, said arms being inclined obliquely from the feed to the discharge end offlthe cylinder, and some of the arms on said rotary shaft being also curved, substantially asset forth.

3. The combination of the cylinder lined at one end with wire-gauze and at the other with emery, the shaft I,journaled in said cylinder, the rubbers M and emery-coated arms E on said shaft, and the fixed arms 0, pr0- jecting between the arms E substantially as set forth.

4:. The combination of the cylinder having a shaft therein provided with rotary rubbers, and counterbalanced deflecting-arms mounted on said shaft, substantially as set forth.

5. The combination, with the cylinder 0 G H and shaft I, carrying rubbing-arms E, of the washers P, having pendent weights N to prevent their rotation with the shaft, and arms 0, projecting upward within the cylinder to assist in throwing the cotton toward the periphery and prevent the clogging of the cylinder, as explained.
